Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years, commonly found in continental crusts.
Uses & applications
Widely used in construction, architectural buildings, countertops, monuments, and paving stones.
Geological facts
Granite is the most common rock of Earth's continental crust and forms the core of many major mountain ranges.
